                                According to the U.S. National Institutes of Health, one cup (8 ounces) of 2% milk contains approximately 1.3 micrograms (mcg) of vitamin B12, providing over half of the daily value for an adult. While whole milk's B12 content is comparable, a single glass contributes significantly to your daily requirements.
